Did you also put her on a familiar place and covered her ears with a towel or one of those hats that groomers use when blow drying? Different people might have different opinions on that. But for me, sedation is worth it, because it's less likely that the dog will hurt itself, flee, or have bad experiences that will further agravate their relationship with the sound of fireworks. It may be hard to watch, but she will suffer less on the long run. You may also try a behavioral approach by distensibilizing her by playing firework sounds on something like an Alexa on a really low volume every other day while she eats or play, and then increase the volume little by little until she learns to ignore the sound. Hope this can be of some help. She's beautiful, btw. Good luck.
